Orange County Bomb Squad investigating acid bombs around Rossmoor home

Bomb Squad investigators are searching for the person or persons who planted several acid bombs in front of a home in Orange County's Rossmore this past weekend.

Four bombs were found in the driveway area of a home in the 3000 block of Mainway Drive on Sunday morning, said Investigator Kent McBride of the Orange County Sheriff's Department.

"They were in the front driveway area. It's hard to say if they were thrown out of a car or set there," McBride said. "I can tell you one was upright, one had already gone off and a couple of others were in the grass on the side."

The one bomb that exploded did so as the resident called 911 for help, the investigator said.

A fifth, incomplete device was found in a tree at nearby Rush Park, located on Blume Drive. Though it also contained acid, derived from common household products, it did not have the ingredient that triggers an explosion, McBride said.

The resident, who is black, told a KTLA reporter she feared she was targeted because of her race.

McBride said there was no evidence at the home, such as hate messages or prior harassment, to suggest the incident was a hate crime.

Typically, the bombs are constructed by kids and the incidents come and go in waves, he said, noting that there have been some similar incidents in the area in recent months.

"There's been a few calls to the Los Alamitos, Seal Beach, Rossmoor area, since mid- August," McBride said. "Can we say they are related? It's hard to say."

The bombs are fairly simple, but can cause a great deal of damage and injury. The most common injuries, McBride said, are to ear drums, hands and the face and eyes.

"(This case) looked more like a very serious prank," McBride said, adding that, "They're all felonies, each one of those bottles."
